Y 5,, a taint intent IIVIPROVEMENT IN GAS-LIGHTING DEVICES.

- The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom it may concern:

Be it known that I, E. P. GLEASON, of the city, county, 'and State ofNew York, have invented, made, and applied to use, a new and usefulInstrument for Lighting Gas; and I dodeclare that the following is afull, clear, and correct description of my invention, reference beinghad to the accompanying drawings, making a part of this specification,and to the letters of reference marked thereon, in which- Figure 1 is aside elevation of my improved instrument for lighting gas, thereceptacle being shown very nearly filled.

Figure 2 isa side elevation of the same, the receptacle being shownnearly empty.

Figure 3 is a view of a modification of the present invention.

In the drawings, like parts of the invention are pointed out by the sameletters of reference.

The nature of the present invention consists in the construction andoperation of a new and useful instrument for lighting-purposes,as morefully hereinafter set forth. Previous, to the present invention, variousinstruments for lighting gas have been employed, among which may becited alcohol-torches of various kinds, instruments supplied withtapers, and lamps filled with oil and supported npon poles.

My invention consists in the use of a proper receptacle, charged withgas, and provided with' a burner,

supplied from said receptacle, the whole contrivance being light andsimple in its operation.

To enable th o'se skilled in the arts to make and use my invention, thefollowing description will sufiice.

' A' shows a case, formed of metal, of any desired. shape, to receiveand protect the reservoir or receptacle B for containing the gas.

B shows the reservoir or receptacle for the gas, placed within the caseA, and corresponding in form with the same. The reservoir or receptaclemay be made of rubber or any elastic material, and in some cases of afibrous'or textile material, rendered gasproof by the applicationthereto of any known agent or agents to effect the result.

C is the handle, to supportthe case A, and

D is an exit-pipe for the gas, inserted about centrally into the top ofthe case A.

The receptacle or reservoir may be provided with a bottom plate, to thecentre of which may be attached a cord, E, while the opposite end of thereceptacle may be confined or secured within the upper portion of thecase A.

G shows a spiral spring, placed directly beneath the reservoir orreceptacle, 'nd resting upon the interior of the case A, or, if preerable, a spiral spring may be used, placed within the receptacle B.

The exit D may be provided with a cock, H, and, when the instrument isin use, it has screwed into it a bent pipe, J, over the forward end ofwhich ispassed As in some cases the pressure of the gasmaybeinsufficient to overcome the spring G, the cord E, one end of whichis attached to the lower portion of the receptacle, may be graduallydrawn down by the hand of the operator, thus expanding the receptacle,as the gas entersthe same. As the receptacle expands, the spring G iscontracted, or, if an interiorspring be used, this spring is expanded.

As soon as the receptacle B has been charged or filled with gas, thecock H maybe closed, and theconnection between the instrument and thegas-burner or other source of supply cut oif, when the bent pipe J maybe inserted in the pipe D. The cock H being again opened, the gas willbe supplied from the receptacle to the burner, which may be 1ighted,andthe instrument may be used for lighting-purposes until the supply of gasbe exhausted.

When the spring Gis used, the function (if this spring,

compressed as it will be while the receptacle B is being charged, is,when the cock H is opened, that gas may be supplied'to the burner, toexpand gradually, and

- thus cause the receptacle to contract as it rises, materiallyassisting the exit of the gas therefrom.

If an internal spring be used, this spring may have one end connected tothe bottom of the reservoir or receptacle, upon its interior, and its.opposite end to the lower ,side of the top plate of the case A. In thiscase, as the receptacle is charged with gas, the-spring is expanded,and, when the cock is opened for the exit of the gas, the contraction ofthis spring causes the receptacle to contract, thus facilitating andkeeping up the supply of gas thence to the burner.

1n fig. 3, a modification of the invention is shown, in which the casefor the receptacle may be made of two hollow tubes, united together, soas to form a gas-tight joint between them or at their point of jointure.In this case, the inten'or spring has one end attached to the under sideof they top plate of the upper section, while its opposite end isattached, about centrally, to the bottom of the receptacle B. As thereceptacle is charged with gas, this spring is expanded, and as the gasis supplied to the burner the contraction of the spring draws thereceptacle outside in, upward, so that the receptacle follows the gas,as it were, in its exit, and supplies its place, thus travelling fromthe lower to the upperksection.

Anyi'ormof case may be used, although I prefer the. round or.circularform, care being taken that the case shall be made, like the receptacle,gas-tight, While the I The value of the invention is found in the easewith ":nected thereto, for lighting-puiposes, Whether the same size ofboth will depend, in a great measure, uponthe number of burners to belighted.

which it can be operated and supplied with gas, and the low cost to theconsumer, the rapid evaporation of alcohol, and the cost of Wax tapersso generally used, being, of course, considered.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-- '1'.Charging or filling an elastic gas-tight receptacle with gas, and thensupplying the same to a burner conshall be accomplished in the precisemanner shown, or in an equivalent manner.

2. The combination, with an elastic gas-tight reservoir, B, of asuitable case, A, and an exit-pipe, D, constructed and operatingsubstantially as described, for the purposes specified.

3. The combination of an elastic gas-tight reservoir or receptacle, B,case A, and exit-pipe D with a spring, G, placed either within orbeneath the receptacle B, for the purposes fully described.

4, The combination of the case A, receptacle B, exitpipe D, and spring Gwith the cord E, for the purposes set forth.
